All vehicles with storage now drop that storage when destroyed (rowboat, RHIB, hot air balloon, both submarines, modular cars). Modular cars already did this, but the others did not. Note this does not include fuel, or modular car engine parts. Renamed carsdroploot convar to vehiclesdroploot - now affects all listed vehicles.
Rename needsVehicleTick back to isMobile, and make it always true for BaseVehicle and its subclasses (this makes it true on CardTable and Sofa unnecessarily, but better that than have it unticked by mistake elsewhere)
Fix for modded servers that have modified the maximum stack size, where players then load >12 rockets into an MLRS, and the MLRS tries to shoot rockets that it doesn't have tubes for, causing IndexOutOfRangeException in FireNextRocket.
